First, the temperature management: This stage should maintain the appropriate temperature, prevent the greenhouse temperature is too high or too low. The appropriate temperature range for flowering and podging of lentils is 16-27°C, with 18-25°C being the most suitable. When the temperature is lower than 15°C and higher than 28°C, it will be detrimental to flowering and scarring, and it will aggravate flowering and falling. Especially when it is higher than 32°C, it not only causes a large number of falling flowers, but also seriously affects the quality of the products. When the shelf temperature is higher than 28°C, it is necessary to ventilate and cool down.
Second, fertilizer and water management: lentils in the early flowering period and sit fruit before, not watering, nor fertilizer. When the first inflorescence was sitting on the beak, it began to top up with water. Under mulching film-mulching conditions, it is advisable to use a method of pouring dark water under the membrane, and to apply quick-acting fertilizer or decomposed human excrement with water. Haricot bean prefers nitrate nitrogen rather than ammonia nitrogen. The application of ammonia nitrogen fertilizer will inhibit plant growth and development. Therefore, when rushing to flowering and applying fertilizer, urea, ternary compound fertilizer and human waste are applied more. In the lower inflorescence, the last inflorescence, usually 12 to 15 days, watering and topdressing, each time, the application of ternary compound per acre. About 10 kg of fertilizer, or 100 kg of human waste. In the middle of the inflorescence of the inflorescence stage, it is usually 8 to 10 days watering and topdressing 1 times, each time applying urea 7 to 8 kg per mu. Inflorescence of the upper inflorescence, the period of pods, and the period of collateral turning and flowering, usually about 10 days, watering and topdressing 1 times, each applying 5 kg of urea and potassium sulfate. In order to improve the light transmission conditions in the middle and late stages of scarring, the yellow leaves in the middle and lower parts should be removed in time, and some leaves should be removed and the late buds should be wiped off at the dense leaves and stems.
